EXPERIlVIENTAL REBUILDING OF A CROSSING WITH TRAFFIC LIGHT SYSTEM INTO A ROUNDABOUT IN SZÉKESFEHÉRVÁR

Abstract

This article is about a new experiment and its results. The aim of this experiment was to analyse and compare the traffic stream in two different traffic control systems (a crossing with full mask traffic libht system and a compact roundabout). The comparability condi- tion was that the conditions, which haye an effect on traffic stream, had to be permanent, and only the traffic control system, had to be changed. The rebuilding of the crossing was made during the night, so the function of the crossing in the road network, the traffic flow, the number of arms, the visibility and the environment of the crossing did not changed. W2e point out that we planned to make these changes on a location, where the rebuilding was not a pressure of circumstances, so both the traffic light system and the roundabout was acceptable. We believe that in practice decision should have been made to choose from these two traffic control methods by making complex evaluation of all the major factors.
